Investigating the Cognitive Response of Brake Lights in Initiating Braking Action Using EEG

Half of all road accidents result from either lack driver attention or maintaining insufficient separation between vehicles. Collision the rear, in particular, has been identified as most common class accident UK, and its influencing factors have widely studied for many years. Rear-mounted stop lamps, illuminated when braking, are primary mechanism to alert following drivers need reduce speed brake. This paper develops a novel brain response approach measuring subject reaction different brake light designs. A variety off-the-shelf assemblies tested physical simulated driving environment assess cognitive times 22 subjects. Eight pairs LED-based two incandescent bulb-based used electroencephalogram (EEG) data recorded. Channel Pz is utilised extract P3 component evoked during decision making process that occurs participant decides lift their foot accelerator depress EEG analysis shows both lights statistically slower evoke responses than lights. Between LED designs, differences evident, but not significant, attributed significant amount movement artifact signal.
